Abstract

In a process of producing cupric hydroxides, products having a high stability in storage will be obtained if phosphate ions are added to a suspension of copper oxychloride in an aqueous phase, the copper oxychloride is then reacted with alkali metal hydroxide or alkaline earth metal hydroxide, and the cupric hydroxide precipitated as a result of the suspension is washed and then re-suspended and subsequently stabilized by the addition of acid phosphate to adjust a pH value of 7.5 to 9. The suspended copper oxychloride is preferably reacted in the presence of phosphate ions in an amount of 1 to 4 grams per liter of the suspension and at a temperature of 20 DEG to 25 DEG C. and the resulting cupric hydroxide is stabilized with phosphate ions in an amount of 3 to 6 grams per liter of the suspension.
